EAR, DEVICE.

Specification of Letters Patent.

Patented July 12, 1921.

Application flled'May 4,1920. Serial No. 378,896.

To all whom it may concern Be it known that I, CHARLES T. BUCK, acitizen of the United States,residing at WVaukegan, in the county'ofLake and State of Illinois, have invented new and useful Improvements inEar Devices, of which the following is a specification.

This invention relates to an ear device and more particularly to adevice so constructed as to aid a person whose hearing is affected toreadily detect the slightest sound.

An object of the invention is the construction of a simple device of fewparts that cannot very readily get out of order for collecting soundWaves, concentrating same, and passing the concentrated waves toward thedrum of the car so that the concentrated wave energy may properlyactuate the drum of the ear.

A feature of my invention is the adjustable feature of the soundamplifier so that the communication of the sound waves on the drum ofthe car may be regulated.

With these and other objects in view the invention will be betterunderstood from the following detailed description taken in connectionwith the accompanying drawing wherein:

Figure 1 is a front elevation of the device.

Fig. 2 is a sectional view.

Fig. 3 is a rear elevation.

Again referring to the drawing illustrating one construction of myinvention the numeral 1 designates a sound receiver consisting of acasing 2 having one end shaped to provide a spherical sound chamber 3while the other end opens through a plate 4 shaped somewhat similar tothe human ear. A sound tube 5 is shaped and arranged in position to haveone end 6 arranged in the sound chamber 3 while the other end 7 isshapedand arranged to be inserted into the sound passage of the ear. Asfar as I have proceeded it will be seen that sound waves will bedirected into the chamber 3 from whence they will pass through the tubeinto the sound passage of the ear. To increase this action I provide thesound amplifier 8 which is in the shape of a bell and provided with aneck 9 slidable on the tube. I provide an adjusting screw 10 for fixingthe position of the bell 8 with relation to the walls of the soundchamber thereby increasing or decreasing the sound effect.

It is, of course, to be understood that the invention may be constructedin various other manners and the parts associated in different relationsand, therefore, I do not desire to be limited in any manner except asset forth in the claims hereunto appended.

Having thus described my invention what I claim is:

1. An ear device comprising a sound re ceiver consisting of a casing oneend of which is spherical shape to form a spherical sound chamber, and asound tube having one end arranged exterior of the casing and one endarranged in communication with said sound chamber, a sound amplifier forpassingsound waves from the chambcrinto the tube, and a device foradjusting said sound amplifier for regulating its position relative tosaid spherical sound chamber.

2. In an ear device, a sound receiver hav ing one end closed and roundedto form a substantially spherical sound chamber, a

tube having one end opening into said receiver and the other end adaptedto be inserted into the car, a sound amplifier on said tube within saidreceiver and opening out toward said round closed end, and means foradjusting the position of said amplifier relative to said round closedend to regulate sound waves passing through the tube.

3. In an ear device, a sound receiver having a round closed end, a tubehaving one end opening into said receiver toward said round closed endand its other end shaped to be inserted into the car, a sound amplifierslidably mounted upon said tube and adapted to guide sound waves to thetube from the receiver, and an adjustable screw connected to saidamplifier for regulating the distance between said round closed end andthe mouth of the amplifier.

In testimony whereof I afiix my signature.

CHARLES T. BUCK.
